Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547314, here are decompositions:

11 + 31547303 = 31547314
17 + 31547297 = 31547314
47 + 31547267 = 31547314
53 + 31547261 = 31547314
83 + 31547231 = 31547314
137 + 31547177 = 31547314
167 + 31547147 = 31547314
251 + 31547063 = 31547314

Showing the first eight; more decompositions exist.
